Hi everyone,

I recently became the owner of a Seat Leon ST 300 Performance. The car is great—it’s a fantastic all-rounder. However, I do miss a bit of turbo noise. After doing a lot of research on this forum, I’ve learned that the R600 intake offers the best results in terms of power. But I’d prefer more sound over optimal power. So, I see two options:

1. A different air intake
2. The DVX diverter valve

My Leon has a Sound Actuator, which I don’t want to disable. So, I’m wondering if there are any owners here who have experience with a modified intake system combined with the Sound Actuator. Does the Sound Actuator overpower the turbo noise, or is the turbo still clearly audible?

I’d love to hear your experiences! Thanks!
